Description

rflash The rflash command initiates Firmware updates on supported xCAT nodes. Licensed Internal Code (also known as microcode) updates are performed on supported HMC-attached POWER5 and POWER6 pSeries nodes, and POWER7 systems using Direct FSP management.

The command scans the specified directory structure for Firmware update package files applicable to the given nodes and components. And then it will automatically select the latest version for the upgrade. The firmware update files include the Microcode update package and associated XML file. They can be downloaded from the IBM Web site: http://www-933.ibm.com/support/fixcentral/.

The POWER5 and POWER6 systems contain several components that use Licensed Internal Code. The rflash command supports two of these components: the managed system (also known as the Central Electronics Complex, or CEC) and the power subsystem (also known as the Bulk Power Assembly (BPA) or Bulk Power Controller (BPC)). Some POWER5 managed systems can be attached to a power subsystem. These power subsystems can support multiple managed systems. When the rflash command is invoked, xCAT will determine the managed system or power subsystem associated with that CEC and perform the update.

The noderange can be an CEC or CEC list, a Lpar or Lpar list and a Frame or Frame list. But CEC (or Lpar) and Frame can't be used at the same time. When the noderange is an CEC or CEC list, rflash will upgrade the firmware of the CEC or CECs in the cec list. If noderange is a Lpar or Lpar list, rflash will update Licensed Internal Code (LIC) on HMC-attached POWER5 and POWER6 pSeries nodes, and POWER7 systems using Direct FSP management. If noderange is a Frame or Frame list, rflash will update Licensed Internal Code (LIC) of the power subsystem on HMC-attached POWER5 and POWER6 pSeries nodes. The noderange can also be the specified node groups. You can specify a comma or space-separated list of node group ranges. See the noderange man page for detailed usage information.

The command will update firmware for NeXtScale FPC when given an FPC node and the http information needed to access the firmware.

PPC (with HMC) specific:

The rflash command uses the xdsh command to connect to the HMC controlling the given managed system and perform the updates. Before run rflash, please use rspconfig to check if the related HMC ssh is enabled. If enable a HMC ssh connection, please use rspconfig comamnd.

Warning! This command may take considerable time to complete, depending on the number of systems being updated and the workload on the target HMC. In particular, power subsystem updates may take an hour or more if there are many attached managed systems.

Depending on the Licensed Internal Code update that is installed, the affected HMC-attached POWER5 and POWER6 systems may need to be recycled. The --activate flag determines how the affected systems activate the new code. The concurrent option activates code updates that do not require a system recycle (known as a "concurrent update"). If this option is given with an update that requires a system recycle (known as a "disruptive update"), a message will be returned, and no activation will be performed. The disruptive option will cause any affected systems that are powered on to be powered down before installing and activating the update. Once the update is complete, the command will attempt to power on any affected systems that it powered down. Those systems that were powered down when the command was issued will remain powered down when the update is complete.

The flash chip of a POWER5 and POWER6 managed system or power subsystem stores firmware in two locations, referred to as the temporary side and the permanent side. By default, most POWER5 and POWER6 systems boot from the temporary side of the flash. When the rflash command updates code, the current contents of the temporary side are written to the permanent side, and the new code is written to the temporary side. The new code is then activated. Therefore, the two sides of the flash will contain different levels of code when the update has completed.

The --commit flag is used to write the contents of the temporary side of the flash to the permanent side. This flag should be used after updating code and verifying correct system operation. The --recover flag is used to write the permanent side of the flash chip back to the temporary side. This flag should be used to recover from a corrupt flash operation, so that the previously running code can be restored.

NOTE:When the --commit or --recover two flags is used, the noderange cannot be BPA. It only can be CEC or LPAR ,and will take effect for both managed systems and power subsystems.

xCAT recommends that you shutdown your Operating System images and power off your managed systems before applying disruptive updates to managed systems or power subsystems.

Any previously activated code on the affected systems will be automatically accepted into permanent flash by this procedure.

IMPORTANT! If the power subsystem is recycled, all of its attached managed systems will be recycled.

If it outputs "Timeout waiting for prompt" during the upgrade, please set the "ppctimeout" larger in the site table. After the upgrade, remeber to change it back. If run the "rflash" command on an AIX management node, need to make sure the value of "useSSHonAIX" is "yes" in the site table.

PPC (using Direct FSP Management) specific:

In currently Direct FSP/BPA Management, our rflash doesn't support concurrent value of --activate flag, and supports disruptive and deferred. The disruptive option will cause any affected systems that are powered on to be powered down before installing and activating the update. So we require that the systems should be powered off before do the firmware update.

The deferred option will load the new firmware into the T (temp) side, but will not activate it like the disruptive firmware. The customer will continue to run the Frames and CECs working with the P (perm) side and can wait for a maintenance window where they can activate and boot the Frame/CECs with new firmware levels. Refer to the doc to get more details: XCAT_Power_775_Hardware_Management

In Direct FSP/BPA Management, there is -d <data_directory> option. The default value is /tmp. When do firmware update, rflash will put some related data from rpm packages in <data_directory> directory, so the execution of rflash will require available disk space in <data_directory> for the command to properly execute:

For one GFW rpm package and one power code rpm package , if the GFW rpm package size is gfw_rpmsize, and the Power code rpm package size is power_rpmsize, it requires that the available disk space should be more than: 1.5*gfw_rpmsize + 1.5*power_rpmsize

For Power 775, the rflash command takes effect on the primary and secondary FSPs or BPAs almost in parallel.

For more details about the Firmware Update using Direct FSP/BPA Management, refer to: XCAT_Power_775_Hardware_Management#Updating_the_BPA_and_FSP_firmware_using_xCAT_DFM

NeXtScale FPC specific:

The command will update firmware for NeXtScale FPC when given an FPC node and the http information needed to access the firmware. The http imformation required includes both the MN IP address as well as the directory containing the firmware. It is recommended that the firmware be downloaded and placed in the /install directory structure as the xCAT MN /install directory is configured with the correct permissions for http. Refer to the doc to get more details: XCAT_NeXtScale_Clusters
